1 Overview
1.1Introduction
This document provides a high level description of ZXSDR R8862A S7100
(hereinafter ZXSDR R8862A S7100), which is one new compact distributed RRU
(Remote Radio Unit) used in ZTE wireless total solution. The RRU is based on
common ZTE compacted RRU platform.and can work in LTE single mode or Multi-
Mode at the same frequency band.
1.2Benefits
2*2 MIMO Capability, Better Performance
ZXSDR R8862A S7100 is based on new compacted RRU platform and high
efficiency Power Amplifier technology. With two transmitting channels and
four receiving channels, it supports 2*2 MIMO to improve coverage, data
throughput and peak download speed.
Faster deployment
ZXSDR R8862A S7100 is 15L in volume and 17Kg in weight. It is portable to
transport and flexible to install on the pole, tower and wall, thus reducing OPEX.
Higher Efficiency, Lower TCO
ZXSDR R8862A S7100’s PA efficiency can reach up to 45% (The PA efficiency
is different based on different working frequency bands);
It supports dynamic adaptive PA power supply due to the output power, which
reduces power consumption.
It is passive thermal dissipation designed, so it is power saving and less noisy.
Integrated lightning protection unit
ZXSDR R8862A S7100 supports integrated Lightning protection unit (PIB), and
the protection level is 20 KA.

2 Functionality
2.1Physical Appearance
ZXSDR R8862A S7100
2.2Functionality
ZXSDR R8862A S7100 is the remote radio unit of distributed base station. The
signal is transmitted /received through ZXSDR R8862A S7100 to/from base band
processing unit for further processing via standard CPRI interface.
By applying the distributed system, the feeder loss will be eliminated when the radio
unit is positioned close to the antenna. The coverage is enlarged with this solution.
The functions of ZXSDR R8862A S7100 include:
Support the LTE configuration of 1.4MHz/3MHz/5MHz/10MHz scalable
bandwidth defined in 3GPP
Band Supported: band 14
Support 2T4R in one box which can optimize spectrum efficiency greatly and
improve network uplink performance
Support 64QAM modulation in both LTE downlink and uplink
Support transmit power report function for every carrier
Support overload protection function for power amplifier

Support transmit channel switching on/off function
ZXSDR R8862A S7100 software failure will not affect the running of BBU and
other ZXSDR R8862A S7100s which are connected to it.

5 Application Scenarios
R8862A as the Remote Radio Unit (RRU) and Baseband Unit (BBU) comprise
distributed macro eNodeB BS8700.
Typical application scenarios of BS8700 are shown in the following figure:

FCC Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates and can radiate
